arranged [Plecospermece). In Cardiogyne^ the female calyces are 

 independent of each other, and the seeds have a large embryo with 

 foliaceous conduplicate and strongly plicate cotyledons, enveloping 

 each other and covering the incumbent radicle. In Plecospermum^ 

 the female calyces are united externally and the style emerges by a 

 small aperture at the summit. The embryo also has cotyledons 

 incumbent to the radicle and enveloping each other ; but they are 

 thick, fleshy and not plicate. Cardiogyne^ plants of Zanzibar, has 

 globular and sessile female inflorescence. Plecospermum^ like the 

 preceding spinous, but natives of India, has the same pedunculate 

 inflorescence. 



StreUus^ a small Asiatic and Australian tree, has given its name 

 to a secondary group (Strebkce), which differs from the preceding in 

 the female flowers never being collected in spikes or capitules (of 

 glomerules), but almost always solitary.^ The male inflorescence 

 of Strebhs is similar to that of Cardiogyne and Plecospermum, It is 

 this which distinguishes it from Pseudostrehlus^ an Indian tree (?) 

 with male flowers united in a compound cyme, on the multiple 

 ramifications of which they are unilateral, and from Taxotrophis^ a 

 spinous shrub of Java, the male inflorescence of which is peduncu- 

 late catkins, covered with glomerules, analogous to those of 

 Madura. In Phyllochlamys^ spinous shrubs, natives of the same 

 countries as Stt^eblus, the male flowers ^ are collected in a sort of 

 capitule with a thick and very short peduncle, and this capitule 

 is surrounded by large accrescent bracts which form around it a 

 foliaceous involucre. Finally Biphcos, a spinous shrub of Ceylon, 

 the flowers of which are constructed like those of the preceding 

 genera, has the amentiform and stipitate male inflorescence of 

 Taxotrophis, and female inflorescence compound and ramifled 

 (covered with glomerules), nearly like the male inflorescence of 

 Pseudostrehlus, 



Dorstenia (fig, 108-113) has given its name to a small group 

 [Dorsteniece) distinguished from all the preceding genera by the inflo- 

 rescence including flowers of both sexes. This inflorescence, as in 

 many preceding types, consists of glomerules either of male flowers
